Technical Field
[0001] This utility model relates to the field of auxiliary equipment for fruit tree cultivation, and in particular to a three-claw limiter for guiding the growth of tree branches. Background Technology
[0002] During the cultivation of fruit trees, it is often necessary to directionally limit the branches and twigs to facilitate the maintenance and pruning of the fruit trees in the later stages. Usually, during the young fruit tree stage, the opening angle of the three branches of the fruit tree is controlled within the ideal range of 45° to 60° through artificial traction, binding or support, so as to standardize the tree structure.
[0003] In current growth practices, conventional methods for fixing the branch opening angle mostly employ traditional techniques such as binding with bamboo poles, pulling branches with wire, or traction with ropes. These methods generally suffer from inherent defects such as cumbersome and time-consuming operation procedures, low work efficiency, and difficulty in standardization. Furthermore, the stability of the fixed angle is poor due to the easy aging and loosening of materials, making it difficult to achieve long-term and uniform standardized control, and requiring frequent maintenance and adjustments.
[0004] Therefore, to address the above problems, a three-claw limiter can be designed to guide the growth of tree branches. It can be quickly and firmly fixed to the trunk, and through three sets of limit frame structures with freely adjustable direction and angle, it can accurately limit and fix the three branch branches of the fruit tree, thereby guiding the branch branches to achieve directional and stable growth within the ideal growth angle range of 45° to 60°. Utility Model Content
[0005] In order to overcome the inherent defects of traditional methods for fixing the opening angle of branches, such as complicated and time-consuming operation procedures, low work efficiency, and difficulty in standardization, as well as the poor stability of the fixed angle due to the easy aging and loosening of materials, it is difficult to achieve long-term and uniform standardized control and requires frequent maintenance and adjustment.
[0006] The technical solution of this utility model is as follows: a three-claw limiter for guiding the growth of tree branches, including a main support, a support platform, a mounting bracket, a rotating shaft, a limit frame, a clamping component, and a fixing component. The support platform is fixedly installed on the upper end of the main support by bolts. There are three sets of mounting brackets, and all three sets of mounting brackets are rotatably connected to the upper part of the support platform. The rotating shaft is rotatably connected to the inside of the mounting bracket. The limit frame is fixedly installed on the periphery of the rotating shaft. Each set of limit frames has a clamping component at one end. There are two sets of fixing components, and the fixing components are located on the periphery of the main support.
[0007] Preferably, the main support can be fixed to the trunk of the fruit tree by setting a fixing component. The main support is used to install and fix the support platform. The support platform supports and installs the three sets of mounting brackets. The three sets of mounting brackets can rotate freely on the support platform. The direction of the three sets of limiting frames can be adjusted to correspond to the three branches of the fruit tree. The clamping components at one end of the three sets of limiting frames can clamp the three branchlets of the fruit tree respectively. The rotating shaft allows the limiting frames to rotate freely inside the mounting support, and the angle of the limiting frames can be freely adjusted. Thus, the limiting frames guide and limit the growth angle of the fruit tree branches.
[0008] Preferably, one side of the main support frame is an arc-shaped structure, and rubber pads are provided on both the arc-shaped surface of the main support frame and the lower end of the support platform.
[0009] As a preferred option, the upper end of the support platform is provided with multiple sets of reserved holes evenly arranged around the axis, and each set of mounting brackets has a through hole corresponding to the reserved hole on its surface.
[0010] Preferably, the inside of the rotating shaft is provided with a rectangular groove, and a fixed plate is slidably connected inside the rectangular groove. A first spring is fixedly installed between the fixed plate and the inner wall of one end of the rectangular groove.
[0011] Preferably, one side of the mounting bracket has multiple sets of insertion holes evenly arranged around the axis of the rotating shaft, and one side of the fixing plate has multiple sets of insertion rods corresponding to the insertion holes.
[0012] Preferably, the clamping assembly includes a connecting frame, a clamping plate, and a second spring. Two sets of connecting frames are provided, and the two sets of connecting frames are symmetrically and slidably connected inside the limiting frame. A clamping plate is fixedly installed at one end of the connecting frame, and a second spring is fixedly installed between the connecting frame and the limiting frame.
[0013] Preferably, the fixing assembly includes a stainless steel strap and a fixing plate. One end of the stainless steel strap is fixedly installed on one side of the main support, and the fixing plate is fixedly installed on the other side of the main support. The other end of the stainless steel strap is fixedly connected to the fixing plate by bolts.
[0014] The beneficial effects of this utility model are: By rotating the three sets of mounting brackets freely on the support platform, the direction of the three sets of limiting frames is adjusted to correspond with the three branches of the fruit tree. Then, using the cooperation of the reserved holes and through holes, common pins or bolts are used to fix the mounting brackets after the angle adjustment. Then, the fixing plate is pulled and the first spring is stretched, causing the insertion rod to leave the insertion hole. The rotating shaft can then be rotated freely to adjust the angle of the limiting frame. After the limiting frame is adjusted, the fixing plate is released, and the first spring contracts to provide tension, allowing the insertion rod to be stably inserted into the insertion hole, locking the rotating shaft. At this time, the two sets of clamps are located on the outer periphery of the branch. The second spring provides pressure to the clamps through the connecting frame, which can clamp the branch, thereby fixing the limiting frame on the outer periphery of the branch. The limiting frame guides and limits the growth angle of the fruit tree branches. The whole installation and disassembly is convenient and can be reused. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] Please see Figure 1 and Figure 2This utility model provides an embodiment: a three-claw limiter for guiding the growth of tree branches, including a main support 1, a support platform 2, a mounting bracket 3, a rotating shaft 4, a limiting frame 5, clamping components, and fixing components. The support platform 2 is fixedly installed on the upper end of the main support 1 by bolts. Three sets of mounting brackets 3 are provided, each rotatably connected to the upper part of the support platform 2. The rotating shaft 4 is rotatably connected to the inside of the mounting bracket 3. The limiting frame 5 is fixedly installed on the periphery of the rotating shaft 4. Each set of limiting frames 5 has a clamping component at one end. Two sets of fixing components are provided, located on the periphery of the main support 1. By setting the fixing components, it is possible to... The main support 1 is fixed to the trunk of the fruit tree. The support platform 2 is installed and fixed by the main support 1. The support platform 2 supports and installs three sets of mounting brackets 3. The three sets of mounting brackets 3 can rotate freely on the support platform 2. The direction of the three sets of limiting frames 5 is adjusted to correspond to the three branches of the fruit tree. The clamping components at one end of the three sets of limiting frames 5 can clamp the three branching branches of the fruit tree respectively. The rotating shaft 4 allows the limiting frames 5 to rotate freely inside the mounting bracket 3. The angle of the limiting frames 5 can be freely adjusted, thereby guiding and limiting the growth angle of the fruit tree branches through the limiting frames 5.
[0018] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, one side of the main support 1 has an arc-shaped structure, and rubber pads 6 are provided on both the arc-shaped surface of the main support 1 and the lower end of the support platform 2. The arc-shaped structure of the main support 1 can fit more closely to the tree trunk, and by providing rubber pads 6 for direct contact with the tree trunk, it can increase friction to prevent slippage and protect the surface of the tree trunk to reduce wear. The upper end of the support platform 2 has multiple sets of reserved holes 201 evenly arranged around the axis, and each set of mounting brackets 3 has a through hole 301 corresponding to the reserved hole 201. Through the cooperation of the reserved holes 201 and the through holes 301, common... Pins or bolts are used to fix the mounting bracket 3 after angle adjustment; the clamping assembly includes a connecting frame 501, a clamping plate 502, and a second spring 503. Two sets of connecting frames 501 are provided, and the two sets of connecting frames 501 are symmetrically slidably connected to the inside of the limiting frame 5. A clamping plate 502 is fixedly installed at one end of the connecting frame 501, and a second spring 503 is fixedly installed between the connecting frame 501 and the limiting frame 5; by moving the two sets of clamping plates 502 to the outside of the tree branch, and by setting the second spring 503 to provide pressure to the connecting frame 501 and the clamping plate 502, the tree branch can be clamped, thereby fixing the limiting frame 5 to the outside of the tree branch.
[0019] Please see Figure 3 , Figure 4 and Figure 5In this embodiment, a rectangular groove 401 is provided inside the rotating shaft 4, and a fixed plate 403 is slidably connected inside the rectangular groove 401. A first spring 402 is fixedly installed between the fixed plate 403 and the inner wall of one end of the rectangular groove 401. Multiple sets of insertion holes 404 are evenly arranged around the axis of the rotating shaft 4 on one side of the mounting bracket 3. Multiple sets of insertion rods 405 corresponding to the insertion holes 404 are fixedly installed on one side of the fixed plate 403. When it is necessary to rotate the rotating shaft 4 to adjust the angle of the limiting frame 5, the fixed plate 403 is pulled forcefully and the first spring 402 is stretched, causing the insertion rods 405 to leave the insertion holes 404. This allows the rotating shaft 4 to be freely rotated to adjust the angle of the limiting frame 5. After adjustment, the fixing plate 403 is released, and the first spring 402 contracts to provide tension, allowing the insertion rod 405 to be stably inserted into the insertion hole 404, locking the rotating shaft 4 and ensuring that the limiting frame 5 stably limits the tree branch; the fixing component includes a stainless steel strap 701 and a fixing plate 702. One end of the stainless steel strap 701 is fixedly installed on one side of the main support 1, and the fixing plate 702 is fixedly installed on the other side of the main support 1. The other end of the stainless steel strap 701 is connected and fixed to the fixing plate 702 by bolts; by wrapping the stainless steel strap 701 around the tree trunk and connecting and fixing it to the fixing plate 702 by bolts, the main support 1 can be fixedly tied to the appropriate position on the tree trunk.
[0020] During operation, two sets of stainless steel straps 701 are wrapped around the tree trunk and then connected and fixed to the corresponding fixing plate 702 with bolts, thereby fixing the main support 1 to the appropriate position on the tree trunk. This allows the curved surface of the main support 1 and the rubber pad 6 at the lower end of the support platform 2 to contact the tree trunk. On the one hand, this increases friction to prevent slippage, and on the other hand, it protects the surface of the tree trunk and reduces wear. The three sets of mounting brackets 3 are moved freely on the support platform 2 to adjust the direction of the three sets of limiting brackets 5 to correspond to the three branches of the fruit tree. Then, by using the cooperation of the reserved hole 201 and the through hole 301, common pins or bolts are used to fix the mounting brackets 3 after the angle adjustment is completed. Then, pull the fixing plate 403 and stretch the first spring 402, causing the insertion rod 405 to leave the insertion hole 404. The rotating shaft 4 can then be freely rotated to adjust the angle of the limiting frame 5. After the limiting frame 5 is adjusted, release the fixing plate 403. The first spring 402 contracts to provide tension, allowing the insertion rod 405 to be stably inserted into the insertion hole 404, locking the rotating shaft 4. At this time, the two sets of clamps 502 are located on the outer periphery of the tree branch. The second spring 503 provides pressure to the clamps 502 via the connecting frame 501, which can clamp the tree branch, thereby fixing the limiting frame 5 on the outer periphery of the tree branch. Thus, the limiting frame 5 guides and limits the growth angle of the fruit tree branches.
[0021] Through the above steps, the three sets of mounting brackets 3 rotate freely on the support platform 2, adjusting the direction of the three sets of limiting frames 5 to correspond to the three branches of the fruit tree. The limiting frames 5 rotate freely inside the mounting brackets 3 via the rotating shaft 4, allowing the angle of the limiting frames 5 to be freely adjusted. Thus, the clamping components at one end of the three sets of limiting frames 5 clamp the branches of the fruit tree, guiding and limiting the growth angle of the fruit tree branches. This solves the inherent defects of traditional methods for fixing the opening angle of branches, such as cumbersome and time-consuming operation procedures, low work efficiency, and difficulty in standardization. Furthermore, the stability of the fixed angle is poor due to the easy aging and loosening of materials, making it difficult to achieve long-term and uniform standardized control and requiring frequent maintenance and adjustment.
[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
